Module parameter Input voltage 6-40V   Module nature: synchronous rectification non-isolated buck constant current constant voltage module CC CV charging module   Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-hydrogen battery (battery pack) charging, solar panels, wind turbines   Input voltage: 6-40VDC   Output voltage: continuously adjustable (1.2-35VDC) for longer than 32V (applicable for applications where the input voltage is higher than the output voltage cannot be boosted)   Output current: Zui is 20A for a long time 15A (power tube temperature exceeds 65 degrees, please add fan cooling, high voltage output please derate)   Current limiting range: 0.2-20A (adjustment) module over 65 degrees, please add a fan.   Zui low dropout: 3V   Working frequency: 150KHZ   Conversion efficiency: ZUI is about 96% higher. Efficiency is related to pressure difference and usage environment.   Output ripple: Ripple around 50mV (no noise) 20M bandwidth (for reference only) Input 24V measured   Working temperature: -10 °C to +75 °C) (Please pay attention to the power tube temperature for actual use. If the temperature is too high, please use heat dissipation or derating)   Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)   Output short circuit protection: There is (instantaneous protection) constant current (current constant current value cannot be short-circuited for a long time)   Input reverse connection protection: none,   Output anti-reverse perfusion: None, for the load self-charged or inductive load needs to add a 2-pole tube!   Wiring method: terminal block   Module size: 60*53*30MM   Output current regulation method:   1. Adjust the CV potentiometer and set the output voltage to the voltage you need according to your load requirements.   2. Set the CC potentiometer counterclockwise for about 30 turns (ie set the output current to be small), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after the battery is discharged, it will be connected to the output and adjust CC to the current you need. (Be sure to use the battery after charging to charge, because the battery is left in the battery.) More, the charging current is smaller.)
